Possible spoilersAh, I remember Heathcliff. I used to watch the show all the time when it was on Nickolodeon when I was still a kid. I also remember the movie. Basically, Heathcliff is forced to babysit his nephews, and spends the time recounting his adventures, thus showing episodes from the series, such as one episode where he meets a cat who looks just like him, one where he winds up working for a mob boss(the Catfather), one where his dad gets released from prison but he thinks he escaped, one where he actually tries to be good, and a few others. Although people who've seen the show before won't find anything new, people who haven't seen it before should at least check it out since it's really just a "best episodes" collection. Although I wouldn't go searching it out, it is a nice little show to watch every now and then.
